The 'field list' feature is necessary if you don't want to transfer all fields to mysql.

In my specific case I want to transfer records from access to an existing mysql table which already have data. In order to do this I need to let mysql take care of the (mysql autoincremented) id field for the new records, otherwise they might be in conflict with existing data.

I can only do this by omitting the id-field from the insert statement - so I need to explicitly specify which fields the inserts are about, otherwise mysql wont understand that I'm omitting the id-field.
